FILE - In this Aug. 30, 2012, file photo, Florida Sen. Marco Rubio addresses the Republican National Convention in Tampa, Fla. The Hispanics with the highest profiles in this year’s political conventions stand as opposites in a cultural and political split that has divided millions of U.S. Latinos for decades. Cuban American Rubio introduced Mitt Romney at the GOP convention. San Antonio Mayor Julian Castro, a Mexican-American, delivered the Democrats’ keynote speech in Charlotte, N.C. They are often lumped together as Hispanics. But Rubio and Castro are emblematic of acute political distinctions between Cuban-Americans and Mexican-Americans. (AP Photo/J. Scott Applewhite, File)
